My thought is it is a problem with their projector at the theater not reading the audio corretly because the DCP file for sure has all 5.1 and they play back on a computer with audio.
That would be pretty weird, though I know a small club cinema whose staff a sometime forgot to switch on their L/R amp and so played center only for a few months. As the center carries the most important dialog, and usually 'some music' as well, nobody noticed.
The issue is probably easy to diagnose per se, the question is, how easy is it for you to go to the cinema and test? I would first use an official channel test DCP, e.g. from Dolby, to be played ahead of your DCP, that should make sure the audio system is setup properly. An 'official' test DCP could also convince staff that there is something wrong...
We had it before though, that people created DCPs with all channels mixed into the center. It can happen based on the specific track layout of your source file. There are ways to check wether the channels are where they belong (e.g. by opening the audio mxf in an audio editor).
Here is a ZIP File with 'official' Dolby 5.1 and 7.1 channel test DCPs (the 5.1 should be sufficient in your case). Make theatre staff play it before your DCP.
